ahmed is sitting on a dock watching a float plane in a harbour. At a certain time, the plane is 350 m above the water and 470 m
Pavel [41]

Answer:

The angle of elevation of the plane measured from Ahmed is approximately 36.67°

Step-by-step explanation:

The given parameters of the float plane are;

The height of the float plane above the water, y = 350 m

The horizontal distance of the float plane from Ahmed, x = 470 m

Given that Ahmed is sitting on the dock, by the water, by trigonometric ratios, we have;

The height of the float plane, the distance of the plane from Ahmed and the line of sight forming the angle of elevation of the plane measured from Ahmed, form a right triangle

tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent \ Leg\ length}

Therefore

tan(\theta) = \dfrac{y}{x}

Where;

θ = The angle of elevation of the plane measured from Ahmed

y = The leg of the right triangle opposite the reference angle

x = The leg  of the right adjacent to reference angle

Therefore;

θ = arctan(y/x) which gives;

θ = arctan(350/470) ≈ 36.67°

The angle of elevation of the plane measured from Ahmed, θ ≈ 36.67°.

Simplify the expression where possible. (t 9) -8
makvit [3.9K]

Answer:

\frac{1}{t^{72}}.

Step-by-step explanation:

To solve this problem, we need to simplify the expression (t^{9})^{-8}.

We know that (x^{a})^{b} = x^{ab}

Therefore:

(t^{9})^{-8} =t^{-72} =\frac{1}{t^{72}}.

Why is b ≠ 1 a condition for f(x) = abx (x is a exponent i cant put it for some reason)?
timurjin [86]

Answer:

1^x = 1

Step-by-step explanation:

If b = 1,

It will be a horizontal line:

y = a

Not an exponential curve

Because

y = a(1^x)

1 power anything is 1

y = a × 1

y = a
